The utility model divides the handheld part of the hysteroscope into a detachable handle part 1 and an insertion part 2. When in use, the doctor holds the handle part 1, so the handle part 1 does not need to be inserted into the human body, while the insertion part 2 needs to be inserted into the body to observe the internal situation. During use, the first shell 10 and the second shell 20 need to be connected first. At the same time, the first coupler 12 and the second coupler 22 are coupled to each other, and the imaging module 3 at the end of the insertion tube 23 is connected to the circuit board 11 in the first shell 10. The image information captured by the imaging module 3 can be transmitted back to the circuit board 11, and is transmitted by the circuit board 11 to the display device 4 for observation by medical staff. After completing an examination, the medical staff disconnects the connection between the first shell 10 and the second shell 20, removes the insertion part 2 from the handle part 1, and then discards the used insertion part 2, and disinfects the handle part 1 for reuse. Before the next use, a new insertion part 2 is connected to the disinfected handle part 1 to perform the next examination. In this way, by utilizing the detachable connection relationship between the first shell 10 and the second shell 20, the handle portion 1 and the insertion portion 2 can be detachably connected, thereby avoiding cross infection to the patient and saving use costs.

[0032] In this embodiment, the first shell 10 and the second shell 20 are connected in a plug-in manner, wherein the first shell 10 and the second shell 20 can also be connected in other detachable ways, such as threaded connection, clamp connection, etc.

[0033] A first mating portion 100 is provided on the first shell 10, a first coupler 12 is fixed on the first mating portion 100 and a first plug-in end 120 of the first coupler 12 is exposed on the outside of the first mating portion 100, a second mating portion 200 is provided on the second shell 20, a second coupler 22 is fixed on the second mating portion 200 and a second plug-in end 220 of the second coupler 22 is exposed on the outside of the second mating portion 200, and the first mating portion 100 and the second mating portion 200 are detachably connected in a plug-in manner; when the first mating portion 100 and the second mating portion 200 are connected, the first plug-in end 120 of the first coupler 12 is in electrical contact with the second plug-in end 220 of the second coupler 22.

[0034] like Figure 4 As shown, specifically, a mating groove 201 is opened on the second mating part 200. When the first mating part 100 is connected with the second mating part 200, the first mating part 100 is mated with the mating groove 201. At this time, the outer peripheral wall of the mating groove 201 is wrapped around the first mating part 100 to ensure the stability of the connection between the first shell 10 and the second shell 20.

[0035] like Figure 3 and Figure 4 As shown, a pair of elastic buckles 202 are symmetrically arranged on the second matching part 200, and a slot 101 for engaging with the elastic buckle 202 is provided on the outer wall of the first matching part 100. Since the elastic buckle 202 is elastic, when the second matching part 200 and the first matching part 100 are matched in place, the elastic buckle 202 automatically engages in the slot 101, thereby preventing the second matching part 200 from automatically separating from the first matching part 100 and causing risks in the operation.

[0036] The elastic buckle 202 is formed by the side wall of the matching groove 201 extending inwardly in the radial direction, and the side wall of the matching groove 201 is provided with a break 203. The break 203 is distributed on both sides of the elastic buckle 202, so that the elastic buckle 202 is more easily deformed elastically.

[0037] A through opening 204 is formed on the bottom wall of the matching groove 201 , and the second plug-in end 220 of the second coupler 22 passes through the through opening 204 and is exposed outside the second matching portion 200 .

[0038] A mounting channel 205 is formed in the second matching portion 200 , and the second coupler 22 is fixed in the mounting channel 205 .

[0039] The first matching portion 100 is formed with a mounting groove 102 for mounting the first coupler 12 .

[0040] The insert tube 23 is provided with a water inlet channel (not shown in the figure) and a water outlet channel (not shown in the figure) extending through the insert tube 23 along its axial direction, and a water inlet hole (not shown in the figure) and a water outlet hole (not shown in the figure) are provided at the end of the insert tube 23.
